SPINNING AND DOUBLING- FRAME.

Specification of Letters Patent.

Patented May 7, 1912.

Application filed March 18, 1911. Serial No. 615,376.

To all whom it may concern:

Be it known that we, ALBERT EDWARD DREW, of 566 Chorley Old Road, Josnrn AnKINsTALL, of 3 Blackburn road, WILLIAM DEAN, of 2 Joseph street, and JOHN HENRY IIOWARTH, of 96 .Ashworth Lane, all of Bolton, in the county of Lancaster, England, and subjects of the King of Great Britain, have invented certain new and use ful Improvements in and Relating to Spinning and Doubling Frames, of which the following is a specification.

Our inventionrefers to improvements in frames of the ring and flier type for spinning and doubling cops on the bare spindle, and particularly to those frames in which spindles are mounted loosely but controlled in driven tubes or sockets, and the ring twisters carrying loose travelers, or alternatively guide eyes or slots are driven separately, the sockets with the loose but controlled spindles being driven at a quicker speed than that of the driven ring twisters.

Our present improvements consist essentially of a particular method of mounting and driving the cylinders or tin drums from which the wharves respectively of the spindle sockets and ring twisters are driven in order to obtain a rising and falling motion of the tin drum which drives the spindle sockets.

In the accompanying two sheets of drawings, Figure 1 is a front elevation of part of a spinning or doubling frame embodying our improvements. Fig. 2 is a plan taken on the plane of the line AB Fig. 1 to show the rising and falling drum which drives the spindles. Fig. 3 is an end elevation and Fig. 4: a front elevation illustrating the method of driving the rising and falling cylinder or tin drum from the upper and stationary tin drum.

In these views :-a designates the frame of the machine; 6 the bottom row of drawing rollers; 0 guides over which the threads (I pass on their way to the ring twisters e; f the loose but controlled spindles; g the driven tubes or sockets; It the stationary rail which carries the ring twisters e; i the lifting rail or frame which carries the spindle sockets; 70 one of the stationary guides for the lifting rail; l one of the chains secured to the lifting rail 2' for raising and lowering the same although any other suitable means may be employed for imparting the required rising and falling motion to the driven spindle tubes and sockets g and spindles f; m the top cylinder or tin drum which is driven in any convenient and known manner by any suitable gearing, not shown, and n the bands by which the ring twisters 6 are driven from the tin drum m.

According to our first improvement we mount the lower cylinder or tin drum 0 in suitable bearings j on the crossstays t" which connect the lifting rails z and form them into a rectangular frame. On the axle m of the top drum on we pivot an arm 7] and on the axle 0 of the rising and falling drum 0 we pivot a second arm g and connect the free extremities of these arms 79 g by a suitable pivotal connection such as a stud or bolt 1". On each of the axles m and 0' We fix a single grooved rope pulley m and 0 respectively and on the center 7" we mount loosely a two grooved rope pulley s.

we pass a driving rope or band t around the groove of the pulley m over the first gfioove of the pulley 8, around the groove of grooved pulley m to complete the circuit.

In this manner as the tin drum on rotates in the direction indicated by the arrow in Fig. 3 it rotates through the bands n the ring twisters e and through the driving rope or band It drives in the same direction the rising and falling tin drum 0, which drives by a series of bands u the wharves g of the spindle sockets 9. As the tin drum 0 falls with the lifting rails 2', the center 1" brings in the two grooved pulley s and so compensates the driving rope or band t for the increased distance apart of the single grooved pulleys m and 0 In like manner when the tin drum 0 rises with the lifting rails 2' and the center 0" is carried outward by the closing of the arms 79 and Q the reverse action and compensation takes place.

Although we have described two single grooved pulleys m 0 on the tin drum axes and a double grooved pulley s on the center r which connects the two pivoted arms 10 g, it will be readily understood that we may employ pulleys with two or more grooves on each drum axle and a pulley with any required and corresponding number of grooves on the pivotal center 7* when more adhesion or driving power is desired.

It will be obvious that we may change the relative diameters of the grooved pulleys in order to drive the rising and falling tin drum 0 at any speed desired in accordance with the count of yarn being spun.

What we claim is 1. In apparatus of the class described, in combination a stationary rail, ring twisters mounted thereon, a drum, driving means between said drum and said ring twisters, a lifting rail, means for raising and lowering said lifting rail, spindle sockets provided with wharves mounted on said lifting rail, a drum carried by said liftingrail, driving means between said second mentioned drum and said wharves, an endless driving member for driving one of said drums from the other of said drums, and means for keeping said endless member taut as said second mentioned drum is raised or lowered.

2. In apparatus of the class described, in combination, a stationary rail, ring twisters mounted thereon, a drum, driving means between said drum and said ring twisters, a lifting rail, means for raising and lowering said lifting rail, spindle sockets provided with wharves mounted on said lifting rail, a drum carried by said lifting rail, driving means between said second mentioned drum and said wharves, an arm pivotally mounted on the axle of said first mentioned drum, a second arm pivotally mounted on the axle of said second mentioned drum, a pulley pivotally supported by the free ends of said arms,

an endless transmission member operativcly associated with each of said drums and e11- gaging said pulley.

3. In apparatus of the class described, in combination, a stationary rail, ring twisters mount-ed thereon, a drum, driving means between said drum and said ring twisters, a lifting rail, means for raising and lowering said lifting rail, spindle sockets provided with wharves mounted on said lifting rail, a drum carried by said lifting rail, driving means between said second mentioned drum and said wharves, a pulley fixed to the axle of said first mentioned drum, a second pulley fixed to the axle of said second mentioned drum, an arm pivotally mounted on the axle of said first mentioned drum, a second arm pivotally mounted on the aXle of said second mentioned drum, a pulley pivotally supported by the free ends of said arms, and an endless transmission member passing around all of said pulleys.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
